The marbled goby Pomatoschistus marmoratus, a species inhabiting coastal Mediterranean lagoons, has been studied by measuring its mitochondrial DNA variation. This analysis revealed a Mediterranean west vs east split and, subsequently, an eastern differentiation among the Libyan-Tunisian Gulf, the Adriatic Sea and the Aegean Sea. The high cohesion between the samples collected in the vast area of western Mediterranean contrasts with the genetic mosaic of the more sub-structured eastern Mediterranean. This western homogeneity can not yet be fully explained even if a human-mediated migratory flow, due to a maritime traffic, has been posited. The pattern in the eastern basin revealed a genetic architecture possibly due to the non-migratory habit of the gobid. Within this perspective, the role of the Mediterranean lagoon habitat should be related to how much it amplifies the effects of historical (e.g. past sea-level changes) and environmental (e.g. present-day hydrographic regime) processes as regards the genetic structure of the inhabiting species.
花鲈（Pomatoschistus marmoratus）是一种栖息于地中海沿海泻湖的物种，通过测量其线粒体 DNA 变异对其进行了研究。该分析显示了地中海西部与东部的分裂，随后，利比亚-突尼斯湾、亚得里亚海和爱琴海之间出现了东部分化。在广阔的西地中海地区采集的样本之间的高度凝聚性与更具亚结构的东地中海的遗传镶嵌形成鲜明对比。即使假定由于海上交通存在人为介导的迁徙流，这种西部同质性也不能完全得到解释。东部盆地的模式揭示了一种遗传结构，可能是由于鲻鱼的非迁徙习性。从这个角度来看，地中海泻湖生境的作用应该与它在多大程度上放大了历史（例如过去的海平面变化）和环境（例如当前的水文学）过程对栖息物种遗传结构的影响有关。
